Longhorn sculpin (Myoxocephalus octodecimspinosus Mitchill) Gray sculpin; Hacklehead; Toadfish Jordan and Evermann, 1S9G-1900, p. 1976. Description.—This fish resembles the shorthorn sculpin so closely that the description may be confined to the points of difference between the two. Chief of these is the great length of the uppermost cheek spines, which usually are about four times as long as the spine just below and reach at least as far back as the edge of the gill cover. This serves equally to distinguish the young from the grubby, which is short-horned. All the head spines, too, are so sharp that one must be cautious in grasping one of these fish for it turns its spines rigidly outward by spreading its gill covers. Furthermore the long horns are naked at the tip. The number and arrangement of the head spines is the same as in the shorthorn sculpin (p. 320), hence need not be described, and there are two thorns on each shoulder and a larger one just above the origin of the pectoral fin. The first dorsal fin is higher than the second (in the shorthorn sculpin these two fins are about. Fig. 157.—Longhorn sculpin {Myoxocephalus octodecimspinosus) equally high), of rather different outline from that of the shorthorn (compare fig. 157 with fig. 152), and proportionately shorter though with about the same number of spines (9). The anal fin originates under the second or third ray of the second dorsal instead of under the fifth ray, though these two fins have the same number of rays (15 to 16 dorsal and about 14 anal) in the two fish, and the pectorals are of the same fanlike form. The lateral line of the longhorn sculpin is marked by a series of smooth cartilaginous plates instead of by the prickly scales of the shorthorn, a difference obvious to the touch, and its body is more slender (about five and one-half times as lon
